GSAC Web Services for Earth Sciences

GSAC is web services for discovery of instrumented site information, and of instrument data files, available in an archive, to provide site and instrument information in a variety of standard formats (RINEX, XML, csv, GAMIT, SINEX, Json, png, ...), and to show where (URLs) to download instrumental data and derived-product files.

GSAC is intentionally built to handle many kinds of Earth science data from instruments with Earth locations, and derived products from such data. For example, GNSS receivers for geodesy, tide gages, met stations, tiltmeters, strainmeters. GSAC is installed at 7 data centers in the Americas and 6 in Europe. One agency's GSAC enables search and access across more than 12,800 GPS stations for more than five million data files.

This SF website appears to be all about the (minor) helper program, the GSAC client. See the UNAVCO GSAC web site for useful and complete information about GSAC.
